Young, dumb, and freaking out. Am I pregnant

So my boyfriend and I always have protected sex with a condom, while also using the pull out method. We’re teens and hormones are raging. We had sex on my fertile window... sometimes twice in a day, but hours apart so sperm was dry and dead. What are my chances of being pregnant? He’s never came inside me (sorry tmi) and I’m pretty sure we did the same thing last month and I was fine. So I don’t get what would be any different.
